soil tempature

Is there a university website that updates the current soil temp throughout the ohio-ind region. Once the calendar hits April the phone will go crazy saying WE ARE TOO LATE to apply crabgrass control. I know I can use my own soil gauge. However, I would like to direct the homeowner to a University site so they know the temp is still colder thaen they think----Thanks

What I generally do is make sure that the "thin" lawns get the pre-emergent right out the door. I will then go back in on my next app and put down a second shot of the same.

Your thicker, denser turf can wait longer for that first app, and you can be fairly sure that you will have excellent control, baring any factors, such as disturbing of the soil that would break the barrier, or improper application.

I don't worry about the timing of the forsythia...hell some were blooming in late February.
